在Python

Question

我有一个字符串数组，如下所示：

string = [ [ "this is a sample",
             "this is another sample"],
           [ "The third sample",
             "the fourth one"] ]

但我想将其转换为：

string = [   "this is a sample",
             "this is another sample",
             "The third sample",
             "the fourth one"  ]

我该怎么办？ 我知道我可以通过预先分配字符串并迭代来实现。但是有更简单的方法吗？

Answer 1

你可以尝试使用列表理解。 代码：

string = [ [ "this is a sample",
         "this is another sample"],
       [ "The third sample",
         "the fourth one"] ]

print([_ for i in range(len(string)) for _ in string[i]])

Answer 2

也许使用列表理解。像

这样的东西

string = [s for S in string for s in S]
